PackJS is a web-based JavaScript compressor service that reduces the size of a js source file.
It uses a combination of techniques to achieve a significant compression when compared to other
common methods. See example for an
illustration.
First-order advantages include:
* Faster loading times
* Lower storage requirements
* Source obfuscation (e.g. IP protection)
PackJS was created by Antonio Roldao.
